Subject: [dpdk-dev] [dpdk-dev 1/1] net/ice: Support for GTPU down/up rss configure
Date: Wed, 18 Mar 2020 13:12:10 -0400 [thread overview]
Message-ID: <20200318171210.8051-2-jia.guo@intel.com> (raw)
In-Reply-To: <20200318171210.8051-1-jia.guo@intel.com>
Add GTP PDU uplink/donwlink checking in RSS inpust set configuration,
in order to support l3 src hash for GTPU uplink, while l3 dst hash
for GTPU downlink.
Change-Id: I0cfa92d8bebcfe9ed95444b14549044a01a511d1
